“…Fe-Cr catalyst produced CNTs with a wide pore size distribution between 51 and 169 nm at variable temperatures between 850°C and 1050°C [38]. Palladium catalyst at temperatures between 630°C and 800°C yielded CNTs with diameters ranging from 39 to 109 nm [36] and Ni-Si catalyst produced CNTs with diameters of 37 nm [39]. It is evident from this observation that by careful choice of reaction conditions and catalyst, the CNTs pore size can be manipulated.…”

New synergic behavior is always inspiring scientists toward the formation of nanocomposites aiming at getting advanced materials with superior performance and/or novel properties. Carbon nanotubes (CNT), graphene, fullerene, and graphite as carbon-based are great fillers for polymeric materials. The presence of these materials in the polymeric matrix would render it several characteristics, such as electrical and thermal conductivity, magnetic, mechanical, and as sensor materials for pressure and other environmental changes. This review presents the most recent works in the use of CNT, graphene, fullerene, and graphite as filler in different polymeric matrixes. The primary emphasis of this review is on CNT preparation and its composites formation, while others carbon-based nano-fillers are also introduced. The methods of making polymer nanocomposites using these fillers and their impact on the properties obtained are also presented and discussed.

“…LPG has been explored as precursors as an alternative to conventional hydrocarbon precursors for the production of CNTs in bulk. Several research groups published with this precursor recently [34][35][36]. For this precursor with NiO catalyst, an average diameter of 25 nm was synthesized [37].…”

“…There are several kind of method that were used to deposit ZnO nanostructures such as hydrothermal, dip-coating, immersion and also chemical vapor deposition (CVD). The CVD method can be considered as preferred methods in order to fabricate the ZnO nanostructures due its advantages such as high yield and purity, low cost and ability to adjust the deposition conditions (Pasha, Poursalehi, Vesaghi, & Shafiekhani, 2010).…”

Zinc oxide (ZnO) nanostructures were synthesized via thermal chemical deposition (TCVD) method and applied as the sensing membrane of an extended-gate field effect transistor (EGFET) pH sensor. The ZnO nanostructures undergone a post-deposition heat treatment with the temperature ranging from 200-500 °C for 15 min in air ambient. The influence of the post-deposition heat treatment on the physical and pH sensing characteristics was investigated. The FESEM images showed that the surface morphology of the samples were dependent on post-annealing treatment. The as-deposited sample showed the biggest grain size and non-uniformed structures. Applying the post-annealing heat treatment caused the surface morphology to become denser and uniform. The most ideal temperature for the heat treatment for EGFET pH sensor application was found at 300 °C resulting in a pH sensitivity of 48.2 mV/pH with 0.9646 linearity.

“…Multi-walled carbon nanotubes (MWCNTs) have attracted a widespread interest of researchers owing to their unique structure as well as physical and chemical properties that open a wide range of their potential applications [1][2][3]. Among numerous techniques of MWCNTs synthesis [4][5][6], catalytic chemical vapor deposition (CCVD) [7,8] is the most popular method of their synthesis because it allows one to control their growth and the structure by adjusting reaction conditions (carbon source, reaction temperature, etc.) and catalyst structure (type and size/amount of active phase, chemical nature of the support, etc.).…”

In this work, multi-walled carbon nanotubes (MWCNTs) with significantly different mean diameters were produced by catalytic CVD over Ni and Co-based supported catalysts. Our results indicate that Ni nanoparticles in the Ni/MgO catalyst are responsible for controlling the inner diameters of the carbon nanotubes. Contrary, Co nanoparticles in the Co/MgO catalyst control the outer diameters of MWCNTs. The “base-growth” mechanism and smaller diameters of the MWCNTs grown on the Ni/MgO catalyst are associated with a strong metal-support interaction (SMSI) resulting from NixMg1−xO mixed oxide formation. The concept of the weak metal-support interaction (WMSI) between Co nanoparticles and MgO for the Co/MgO catalyst confirms the “tip-growth” mechanism of the MWCNTs.
